Craig,

I am assuming that when you say "concurrent users", you mean that you want to know how many users were logged on at a given point in time. If so, you can always determine that through LogonOff historically or, as Victor pointed out, through SessionInfo in real time. Historically, you can get the point in time as follows:

select count(*)
  from dbc.logonoff    b
  left outer join
       dbc.logonoff    a
    on a.username      = b.username
   and a.sessionno     = b.sessionno
   and a.logicalhostid = b.logicalhostid

 where b.event = 'logon'
   and (
       (a.event in ( 'logoff', 'forced off')
        and 120000   between b.logontime and a.logtime
        and date-5   between b.logondate and a.logdate)
        OR
        (a.event is null
        and a.logdate||a.logtime <= date-5||120000)
       )

This would give you the number of sessions that were logged on at a point in time, i.e. 12:00:00 five days ago.

Hope this helps.
